Abstract
Description
Die Erfindung betrifft hakenförmige Vorrichtungen zum Anbringen von Gegenständen an einer Wand.The invention relates to hook-shaped devices for attaching objects to a wall.
Derartige Vorrichtungen sind in zahlreichen Formen im Handel und bestehen beispielsweise aus Schraubhaken, die in in die Wand eingesetzte Dübel eingeschraubt werden. Dabei kommt es häufig vor, daß zum Anbringen eines größeren Gegenstandes, beispielsweise eines breiten Bildes, wenigstens zwei solcher Schraubhaken erforderlich sind, die sich nach dem Einschrauben in entsprechende Dübel erfahrungsgemäß nur selten in genau gleicher Höhe befinden, so daß das daran aufgehängte Bild unabänderlich schief hängt. Dieses unbefriedigende Ergebnis rührt meistens daher, daß während des Bohrens der für die Dübel benötigten Löcher der Bohrer wegen des unhomogenen Wandmaterials zur Seite und/oder nach unten wegdriftet, wie jeder Hand- und Heimwerker weiß.Such devices are in numerous forms in the trade and consist for example of screw hooks, the dowels inserted into the wall become. It often happens that the Attaching a larger item, for example a wide picture, at least two of them Screw hooks are required, which are after the Experience has shown that it is screwed into the appropriate dowels are rarely at exactly the same height, so that the picture hung on it invariably crooked hangs. This unsatisfactory result mostly stirs therefore that during drilling the for the Dowels needed holes in the drill because of the inhomogeneous Wall material to the side and / or down drifts away, as every handyman and handyman knows.
Aus der DE 455 765 ist eine Einrichtung zur Befestigung von Spiegelplatten an einer Wand bekannt. Sie besteht aus einer den Plattenrand umfassenden Klaue, die mit einer zylindrischen Bohrung versehen ist, die auf einen Zapfen eines Wandarms aufsteckbar ist, wobei der Wandarm höhenverstellbar an der Wand befestigt ist. Mit dieser Einrichtung sind jedoch lediglich Spiegel- oder sonstige Glasplatten an einer Wand befestigbar. In der WO 97 07720 ist ein Befestigungselement für Bilder odgl. beschrieben. Es besteht aus einem Zwischenstück, das mit einer im wesentlichen vertikal verlaufenden Gewindebohrung versehen ist. Dieses Zwischenstück ist mit einem Befestigungselement an der Wand fixierbar. In die Bohrung ist ein mit einem durchgehenden Gewinde versehener Gewindestab einschraubbar. Das aufzuhängende Bild wird dann auf oder an der Spitze des Gewindestabs abgestützt. Hierbei ist als nachteilig anzusehen, daß zur Befestigung des Zwischenstückes an der Wand ein weiteres Bauteil notwendig ist, jedoch soll das Prinzip der Höhenverstellbarkeit der Aufhängevorrichtung, d. h. das Verdrehen eines Gewindestabes in einer Bohrung, bei der vorliegenden Erfindung verwendet werden.DE 455 765 describes a device for fastening known from mirror plates on a wall. It consists of a plate edge Claw provided with a cylindrical bore is that attachable to a pin of a wall arm is, the wall arm adjustable in height on the Wall is attached. With this facility, however only mirror or other glass plates attachable to a wall. In WO 97 07720 a fastener for pictures or the like. described. It consists of an intermediate piece that with an essentially vertical threaded bore is provided. This intermediate piece is fixable to the wall with a fastener. In the hole is one with a through Threaded threaded rod can be screwed in. The The picture to be hung will then be on or at the top of the threaded rod. This is considered a disadvantage to see that for fastening the intermediate piece Another component is necessary on the wall is, however, the principle of height adjustability the hanger, d. H. the twisting a threaded rod in a hole, in the present Invention can be used.
Der Erfindung liegt die Aufgabe zugrunde, Vorrichtungen der eingangs erwähnten Art anzugeben, mit deren Hilfe jeder Gegenstand genau gerade an einer Wand angebracht werden kann, das heißt mit beispielsweise waagerechtem bzw. senkrechtem Verlauf der Kanten dieses Gegenstandes, wobei hierfür nur einige einfache, auch von einem Laien ausführbare Handgriffe erforderlich sind.The invention is based, devices of the type mentioned at the beginning, with whose help each object is precisely on one Wall can be attached, that is, for example horizontal or vertical course the edges of this item, only for this some simple, even layman executable Handles are required.
Diese Aufgabe wird gemäß Anspruch 1 dadurch gelöst,
daß die Vorrichtungen aus je drei Elementen zusammensetzbar
sind, wobei
Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß der in die Wand eingreifende Teil des ersten Elementes ein Schraubgewinde aufweist, das in einen in eine in der Wand befindliche zylindrische Bohrung eingesetzten Dübel einschraubbar ist.According to an advantageous development of the invention it is intended that the engaging in the wall Part of the first element is a screw thread has that in a in the wall cylindrical bore inserted screw plug is.
Nach einer anderen Alternative ist vorgesehen, daß der in die Wand eingreifende Teil des ersten Elementes eine geriffelte Oberfläche aufweist und in einen in eine in der Wand befindliche zylindrische Bohrung eingesetzten Dübel einschlagbar ist.According to another alternative it is provided that the part of the first element which engages in the wall has a corrugated surface and in one into a cylindrical one in the wall Bore used dowels can be driven.
Es besteht aber auch die Möglichkeit, daß der in die Wand eingreifende Teil des ersten Elementes eine geriffelte Oberfläche aufweist und in eine in der Wand befindliche zylindrische Bohrung eingipsbar oder einzementierbar ist.But there is also the possibility that the in the wall engaging part of the first element has a corrugated surface and in a wall-mounted cylindrical hole plasterable or can be cemented.
Um das in die Wand eingeschraubte erste Element besser ausrichten zu können, ist ferner vorgesehen, daß der aus der Wand herausstehende Teil des ersten Elementes einen rechteckigen, vorzugsweise quadratischen Querschnitt hat, wobei zwei seiner jeweils gegenüberliegenden Seitenflächen parallel zur Achse der Gewindebohrung verlaufen.Around the first element screwed into the wall It is also planned to be able to better align that the part of the first protruding from the wall Element a rectangular, preferably square Has cross section, two of its each opposite side faces parallel to the axis the threaded hole.
Um das erste Element in einen Dübel einschrauben zu können, weist der aus der Wand herausstehende Teil des ersten Elementes an seiner Stirnseite einen die Klinge eines Schraubendrehers aufnehmenden Schlitz, vorzugsweise Kreuzschlitz, auf.To screw the first element into a dowel can, the part protruding from the wall of the first element on its face one Blade of a screwdriver receiving slot, preferably cross recess.
Zum Einschrauben des zweiten Elementes in die Gewindebohrung des ersten Elementes bzw. zum Verstellen des bereits eingeschraubten zweiten Elementes ist vorgesehen, daß der Bolzen und/oder der Zapfen des zweiten Elementes an der jeweils freien Stirnseite einen die Klinge eines Schraubendrehers aufnehmenden Schlitz, vorzugsweise Kreuzschlitz, aufweisen.For screwing the second element into the threaded hole of the first element or for adjustment of the second element already screwed in it is provided that the bolt and / or the pin of the second element on the free end face a receiving the blade of a screwdriver Have slot, preferably cross slot.
Damit der rechtwinklige Haken des dritten Elementes immer von der Wand absteht und sich nicht auf dem Zapfen des zweiten Elementes seitlich wegdrehen kann, ist ferner vorgesehen, daß der Ansatz des dritten Elementes einen rechteckigen Querschnitt hat und bis nahezu an die Wand heranreicht.So that the right-angled hook of the third element always protrudes from the wall and is not on the Turn the pin of the second element away to the side can, it is further provided that the approach of third element has a rectangular cross section has and almost reaches the wall.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß jeder aufzuhängende Gegenstand genau gerade an einer Wand angebracht werden kann, das heißt mit beispielsweise waagerechtem bzw. senkrechtem Verlauf der Kanten dieses Gegenstandes. Hierfür muß lediglich von den zwei verwendeten hakenförmigen Vorrichtungen wenigstens eine durch Verdrehen des zylindrischen Bolzens des zweiten Elementes dieser Bolzen soweit in der Höhe verändert werden, bis die Auflageflächen beider Haken auf gleicher Höhe liegen, wofür nur einige einfache, auch von einem Laien ausführbare Handgriffe mit einem Schraubendreher erforderlich sind.The advantages achieved with the invention exist especially in that every item to be hung to be mounted straight on a wall can, that is with, for example, horizontal or perpendicular course of the edges of this object. To do this, only of the two used hook-shaped devices at least one by rotating the cylindrical pin of the second Element of these bolts has changed in height until the contact surfaces of both hooks are at the same level, for which only a few simple, handles that can also be carried out by a layperson with a screwdriver.
In einer speziellen Ausgestaltung besitzt der Zapfen einen gegenüber dem Bolzen geringeren Durchmesser, so daß im Ergebnis am Übergang zwischen Zapfen und Bolzen als Anschlagsfläche für das dritte Element einen Absatz gebildet wird, der es in vorteilhafter Weise erlaubt, vergleichsweise große Kräfte vom dritten auf das zweite Element zu übertragen.In a special embodiment, the pin has a smaller diameter than the bolt, so that as a result at the transition between tenons and bolts as a stop surface for the third element a paragraph is formed, which makes it more advantageous Way allowed comparatively large forces to transfer from the third to the second element.
Eine Alternative zur Erzeugung eines Anschlages besteht darin, auf dem Bolzen und/oder dem Zapfen koaxial radial überstehende Scheiben oder Ringe anzubringen, die die Funktion eines Anschlages erfüllen. Sie dienen im Hinblick auf den Zapfen als Begrenzung der Einschraubtiefe des zweiten Elementes im herausstehenden Teil (12) des ersten Elementes und auf dem Zapfen als Begrenzung der Einstecktiefe des dritten Elementes hierauf.There is an alternative to creating a stop therein, coaxial on the bolt and / or the pin to attach radially protruding washers or rings, that perform the function of a stop. They serve as a limitation with regard to the pin the screw-in depth of the second element in the protruding part (12) of the first element and on the spigot as a limitation of the insertion depth of the third element thereon.
Beim Anbringen von Gegenständen an der hakenförmigen Vorrichtung gemäß der Erfindung besteht die große Gefahr, daß während des Einfädelns unmittelbar vor dem Einhängen das im allgemeinsten Fall lose aufgesteckte dritte Element versehentlich in axialer Richtung vom Zapfen nach oben herunter geschoben wird, mit der Folge, daß erneut das dritte Element aufzustecken ist und der Einfädelvorgang von neuem zu beginnen hat. Um hier eine Erleichterung zu schaffen, wird eine gegebenenfalls lösbare Verbindung zwischen dem zweiten und dritten Element, beispielsweise eine Verschraubung vorgeschlagen.When attaching objects to the hook-shaped Device according to the invention is the great danger that immediately during threading in the most general case before mounting loosely attached third element inadvertently pushed axially downwards from the pin with the result that the third Element and the threading process has to start again. A relief here to create, is a possibly releasable Connection between the second and third element, for example, proposed a screw connection.
Im Hinblick auf die Abmessungen vom Zapfen relativ zum Bolzen ist von Vorteil, den Durchmesser des ersteren mit 50 bis 75 % von dem des letzteren zu wählen. Hierbei gilt es einen Kompromiß zu schließen: Zum einen sollte der Durchmesser des Bolzens im Vergleich zum Zapfen groß gewählt werden, so daß eine vergleichsweise große Abstütz- und Auflagefläche zur Aufnahme großer Kräfte zur Verfügung steht. Andererseits sollte der Durchmesser des Zapfens jedoch nicht zu klein gewählt werden, um problemlos an der Stirnseite des Zapfens mit einem Schraubendreher angreifen zu können. Wäre der Durchmesser des Zapfens zu gering, wäre der Schlitz zu kurz, um den Schraubenzieher aufnehmen und ein befriedigendes Eindrehen sicherstellen zu können. Im Falle von vergleichsweise kleinen Abmessungen der vorgeschlagenen hakenförmigen Vorrichtung wird man den Durchmesser des Zapfens vergleichsweise groß wählen.Relative to the dimensions of the tenon for bolting is advantageous the diameter of the former with 50 to 75% of that of the latter too choose. A compromise must be made here: First, the diameter of the bolt be chosen large compared to the tenon, so that a comparatively large support and support area is available to absorb large forces. On the other hand, however, the diameter of the pin should be not too small to be chosen without problems on the front of the pin with a screwdriver to be able to attack. Would be the diameter the pin is too small, the slot would be too short to pick up the screwdriver and a satisfactory one To ensure screwing in. In case of comparatively small dimensions of the proposed hook-shaped device becomes the diameter choose a comparatively large pin.
Die Öffnungsweite des dritten Elementes, die zur Aufnahme des über einen Haken anzubringenden Gegenstandes dient, ist bevorzugt so zu wählen, daß sie größer ist als die Stärke des aufzunehmenden Befestigungshakens. Hierbei meint der Begriff "Stärke" im Sinne der Erfindung den Abstand zwischen der vom Haken der Vorrichtung zu durchgreifenden Öffnung und der oberen Begrenzungsflächedes Hakens, gemessen in der Ebene des Hakens. Die Öffnungsweite addiert sich aus dem Radius der Außenfläche des Ansatzes plus den Abstand der inneren Begrenzungsfläche des anderen Schenkels von der Achse der Bohrung. Der entscheidende Vorteil ist, daß der anzubringende Gegenstand, wie zum Beispiel ein Bild, in horizontaler Ausrichtung bei guter Einsehbarkeit eingefädelt werden kann und anschließend um 90° nach unten geklappt wird.The opening width of the third element leading to Picking up the object to be attached using a hook is preferably chosen so that it is greater than the strength of the fastening hook to be picked up. Here the term "strength" means in the sense of the invention the distance between the Hook the device to penetrate through and the upper boundary surface of the hook in the plane of the hook. The opening width adds up itself from the radius of the outer surface of the approach plus the distance of the inner boundary surface of the other leg from the axis of the bore. The key advantage is that the one to be attached Object, such as a picture, in horizontal alignment with good visibility can be threaded and then by 90 ° is folded down.
Beim Anbringen des Gegenstandes könnte sich zudem das Problem ergeben, daß der Gegenstand unterhalb des Hakens, so z. B. am zweiten Element und insbesondere am herausstehenden Teil des ersten Elementes zur Anlage kommt, so daß eine exakte vertikale Ausrichtung nicht mehr ohne weiteres möglich ist. Zur Beseitigung dieses Problemes ist von Vorteil, wenn der Radius der Außenfläche des Ansatzes kleiner ist als der Abstand der inneren Begrenzungsfläche des anderen Schenkels von der Achse der Bohrung. Beträgt diese Differenz mehr als die Dicke des Befestigungshaken des anzubringenden Gegenstandes (gemessen senkrecht zu der durch den Befestigungshaken beschriebenen Ebene) ist eine exakt vertikale Ausrichtung ohne zusätzlichen Maßnahmen möglich.When attaching the item could also the problem arise that the object below of the hook, e.g. B. on the second element and in particular on the protruding part of the first element comes to the plant, so that an exact vertical Alignment is no longer possible. To solve this problem, it is advantageous if the radius of the outer surface of the neck is smaller is the distance of the inner boundary surface of the other leg from the axis of the bore. This difference is more than the thickness the fastening hook of the object to be attached (measured perpendicular to that through the fastening hook described plane) is an exactly vertical one Alignment possible without additional measures.
Schließlich wird noch vorgeschlagen, daß die vom Ansatz und den einen Schenkel gebildete obere stirnseitige Begrenzungsfläche eine horizontale Ebene ist. Bei Verwendung eines entsprechenden, das heißt ebenfalls eine horizontale Kontaktfläche bildenden Befestigungshakens, ergibt sich eine Stabilisierung gegen Drehungen um eine horizontal verlaufende Achse, das heißt ein Verschwenken des anzubringenden Gegenstandes, was besonders dann von Bedeutung ist, wenn nur ein einziger Befestigungspunkt vorgesehen ist. Ein Verschwenken des Gegenstandes, wie z. B. des Bildes wird weitgehend unterbunden; eine exakte horizontale Ausrichtung des Bilderrahmens erübrigt sich. Finally, it is proposed that the dated Approach and the upper leg formed one frontal boundary surface a horizontal Level is. When using an appropriate that is also called a horizontal contact surface Fastening hook, there is a stabilization against rotation around a horizontal Axis, that is, a pivoting of the to be attached Object, especially what of Meaning is if only a single attachment point is provided. Swiveling the object, such as B. the image is largely prevented; an exact horizontal alignment of the There is no need for a picture frame.
